Everything GS Copilot can do

An AI copilot built into your editor.

From a quick question to a multi-file refactor — chat, plan, complete, and apply, all without leaving your spreadsheet.

AI Chat

Ask questions about your project, debug errors, and generate Apps Script code in a chat panel that understands your open files.

✓list files
✓read editor.gs
✓grep "TODO"
apply 3 edits

Agent mode

Describe what you want and let the agent explore your project — list, read, grep, lint — then plan and apply edits across files.

1Scan dependencies
2Draft migration
3Update callers

Plan mode

For bigger tasks the AI lays out a step-by-step plan and can ask clarifying questions before it writes any code.

function totalRevenue() {
  return rows.map(r => r.amt)map(r => r.amt)
}
Tab accept

Inline code completions

Ghost-text suggestions as you type, tuned for Apps Script and the Workspace APIs — Sheets, Docs, Gmail, Drive, Calendar.

// selected
for (i=0; i<n; i++) sum += a[i];
refactor to reduce()
a.reduce((s, x) => s + x, 0)

Quick edit

Select code and ask for a targeted change — refactor, fix, document, or optimize — without ever leaving the editor.

− if (x == null) return;
+ if (x ?? true) return;
+log("guarded");
accept revert

Diff review & one-click revert

Every AI change is shown as a clear, side-by-side diff you approve before it touches your code — and any turn reverts in one click.

AI patchrange.setValue(total);
function saveTotal(row) {
range.setValue(total);
}

AI Code Apply

Apply AI-generated code directly to your project with confidence — clean writes across every affected file.

I was a bit nervous about letting an AI edit my code, but the 'Agent Mode' is amazing. I just tell it what I want, it figures out a plan and then shows me the exact changes before actually making them.

Honestly, this extension has been a lifesaver for my daily workflow. I used to spend half my time switching back and forth between the script editor and an AI chatbot, copying and pasting code until my brain fried.
